Self Diagnosis

I found this Q&A and this is exactly what I have been experiencing so starting today I have entered into a stretching and strengthening routine this article was also encouraging. So yesterday I ran 4k, very slowly and was only in slight discomfort and today I ran 5k at about 6.30min/k pace with slight discomfort and applied the routine mentioned above afterwards. Looks good, hopefully in a month I will be running pain free! but only time, patience and obedience will get me there. next month I think I will continue with these easy short distances to maintain some conditioning, then really hit the straps heading up towards C2B.
